Before the tribute began, the princess, who wowed in a mint green Balmain blazer and pleated white skirt, took her seat in the Royal Box.
She was greeted with applause, and those around her stood and applauded as she was led to the stands.
Minutes later, Kate was on her feet as she stood applauding Federer, who was also welcomed to the box after a video of his achievements was played.
